this is getting closer to the sort of feel we are after. I'm not sure about the blue box in the middle. Also, I would prefer to see the orange used (maybe rather than blue).
I'm not sure about the cross in the middle - the other graphic looks good but the cross feels a bit harsh and medical like.
Also, as we are likely to use this in horizontal banners I do like the logos that are more horizontal with the words to the side (maybe 2 lines). What do you think?
